In a disk apparatus of contact-start-stop system, a head slider carries out a contact-start-stop operation at a non-specified position taken in the radial direction of a disk-shaped recording medium. This can be achieved by entering a random signal from a random number generator to a means for positioning the head slider in the radial direction of the disk when the recording medium begins to stop rotating. Accordingly, the head slider can be effectively inhibited from adhering to the disk, and the disk becomes unlikely to suffer wear, damage and head crash, and further, many information tracks can be formed on the disk.
